Problems solved by technology

[0003] At present, when the smart card is used for offline transactions, the terminal needs to check the validity of the smart card, and the validity check of the smart card includes judging whether the smart card is in the blacklist. With the passage of time, the number of smart card loss reports gradually increased, resulting in a gradual increase in the number of blacklists stored in the terminal, and the time to retrieve the blacklist during offline transactions also increased, reducing the efficiency of offline transactions

Embodiment 1

[0028] This embodiment provides a method for offline transaction timeliness management, see figure 1 ,include:

[0029] Step S1, when the terminal device obtains the application serial number of the smart card, judge whether the application serial number is in the exclusive blacklist stored in the terminal device, if yes, perform error processing; otherwise, execute step S2;

[0030] Step S2, the terminal device obtains the time of the last online transaction from the smart card, and judges whether the time difference between the current consumption time and the last online transaction time is greater than the preset value, and if yes, performs error processing; otherwise, sends an initialization consumption command to the smart card, and executes the steps S3;

[0031] It should be noted that the last online transaction time is specifically the last online transaction time of the smart card; in this embodiment, when the smart card conducts online transactions, the current tr...

Embodiment 2

[0052] The blacklist maintenance method in the management system specifically includes that the complete blacklist and proprietary blacklist are kept in the management system, including:

[0053] Step A1. When the management system receives the loss report application, it obtains the application serial number from the loss report application; and writes the application serial number into the complete blacklist;

[0054] Step A2, the management system queries the transaction record corresponding to the obtained application serial number, and obtains the last online transaction time from the transaction record;

[0055] Step A3, the management system obtains the current server time, and judges whether the time difference between the last online transaction time and the current server time is less than the preset time period, and if yes, write the application serial number into the exclusive blacklist; otherwise, end.

[0056] For example, the preset time period is 12 months, and...

Embodiment 3

[0104] This embodiment provides an offline transaction timeliness management method, in which the terminal device periodically downloads a proprietary blacklist from the background server; see Figure 4 and Figure 5 , including:

[0105] Step 201, the terminal device checks whether the smart card has been inserted into the card reader, if so, execute step 202, otherwise return to step 201;

[0106] Step 202, the terminal device sends an application selection request including the application identifier to the smart card;

[0107] Specifically, the command message format of the application selection request sent by the terminal device is specifically: CLA+INS+P1+P2+Lc+Data+Le; CLA is the command category, INS is the command code, P1 and P2 are the command parameters; Data is Command data field; Lc is the length of the command data field, and Le is the maximum number of bytes of the expected response data;

[0108] In this embodiment, the terminal device calculates the lengt...

Abstract

The invention relates to the field of information security, in particular to an offline transaction time limit management method and an offline transaction time limit management device. The offline transaction time limit management method specifically comprises the steps of: judging whether an application serial number is in an exclusive blacklist stored in terminal equipment when the terminal equipment acquires the application serial number of a smart card; if not, acquiring a last online transaction time from the smart card, and judging whether a time difference between a current consumptiontime and the last online transaction time is greater than a preset value; and receiving initial consumption response sent by the smart card and continuously executing an offline transaction if the time difference is not greater than the preset value. By adopting the offline transaction time limit management method and the offline transaction time limit management device, the control over the blacklist number during the offline transaction process by means of the smart card is realized, the offline transaction time can be effectively shortened, and the offline transaction efficiency can be improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to an off-line transaction timeliness management method and device. Background technique [0002] Smart cards have the function of information processing; due to their inherent information security, portability, relatively complete standardization and other advantages, smart cards have been used more and more in fields such as identity authentication, banking, telecommunications, public transportation, and parking lot management. [0003] At present, when the smart card is used for offline transactions, the terminal needs to check the validity of the smart card, and the validity check of the smart card includes judging whether the smart card is in the blacklist. With the passage of time, the number of smart card loss reports has gradually increased, resulting in a gradual increase in the number of blacklists stored in the terminal, and the time to retrieve the blacklist during of...
